Unknown people with access to House of Commons and federal government computers have been using their time — and taxpayer resources — to make anonymous changes to Wikipedia pages on everything from the Stanley Cup, to soft drinks and flatulence. Even Scooby-Doo is involved.

On Friday, someone using Parliament Hill computers made changes to a Wikipedia page about beans to explain that they can cause lots of gas, according to an Internet bot that tweets anonymous entries to Wikipedia pages from federal government Internet addresses.

The entry on beans initially explained that they have been an important source of protein throughout history. Then, someone on a House of Commons computer address added his or her own touch.

Other computers on the broader federal government network are also being used to tinker with Wikipedia pages.

On Friday, someone accessing a computer on the network for Shared Services Canada — the department responsible for managing the federal government’s IT infrastructure — made changes to a Wikipedia entry on the Nova Scotia Senior Baseball League.

A separate anonymous edit Friday from someone on the Shared Services Canada network made changes to a Wikipedia entry on the “international availability of Fanta” (a fruit-flavoured soft drink) to apparently add that Fanta Zero isn’t available in Canada.

Other recent changes by someone on the Shared Services Canada network included minor edits to a page on the 1946 Stanley Cup Finals.

Someone on the House of Commons network also made a minor change Friday to the Wikipedia entry for Conservative MP Costas Menegakis.

Earlier this week, someone accessing a computer at the Department of National Defence made minor edits to the Wikipedia entry for animated sleuth Scooby-Doo. Other anonymous edits by someone on the DND network included cleaning up typos to the Wikipedia entry on former Alberta premier Alison Redford, and minor edits to a page on the Honda CR-X del Sol.

The Internet Protocol (IP) addresses recorded by Wikipedia indicate the recent changes were made by people accessing the House of Commons computer network and the broader government network used by various departments.

The government allows “limited personal use” of federal networks and devices “that is conducted on personal time, that is not for financial gain, that does not incur any additional costs for the department, and that does not interfere with the conduct of business.”

A spokesperson for federal Treasury Board president Tony Clement, whose department establishes computer protocols for federal employees, said suspected misuse of government computers will be investigated.

“Federal government employees are expected to abide by the Policy on Acceptable Network and Device Use. If misuse is suspected, the incident will be investigated and action will be taken as per the policy,” Stephanie Rea, director of communications for Mr. Clement, said in an email.

The IP addresses used on the House of Commons and federal government networks to make the Wikipedia edits could come from any one of thousands of computers. The House of Commons network alone can be accessed by potentially more than 1,000 people, including MPs, their staff members, Commons officials and even journalists.
